5.0 SETTING PARAMETERS
5.1 S
ET THE SETPOINT TEMPERATURE
To set the oven setpoint temperature, you simply have to set-up the ring nut to the desired temperature,
when the ring nut is repositioned, the display shows the new setpoint temperature for 5 seconds, and the
setpoint LED is ON (see paragraph
) for all the time in which the setpoint temperature is displayed.
After these 5 seconds, the setpoint LED turns off and the display shows the feedback temperature (oven
temperature).
If the ring nut is set under the temperature of 0 °C the thermoregulator turns OFF, therefore disabling the
temperature setting.

HANGE THE TEMPERATURE PROBE
To change the temperature probe you have to enter the configuration menu (see paragraph
), enter the
Prb
), and then select
tEr
if you want to use the
thermoregulator K
,
J
if you want to
use the
thermoregulator J
or
Pt1
if you want to use the
PT100
, then confirm your choice by the OK key.
Once the change is done, exit the menu and connect the temperature probe you have just selected to the
clips of the thermoregulator (see paragraph
), than check that the thermoregulator doesn’t signal any er-
ror (see paragraph
Please note
: for the thermocouple (K or J) be sure to respect clips polarities, as the thermoregulator is not
designed to get if such polarities are respected, therefore it will not signal any error. To understand if the po-
larities are respected you can make a simple test: heat (even of few centigrade) the point of the thermocou-
ple, then, if the temperature shown by the thermoregulator decreases (instead of increasing) it means that
the polarities have been inverted.
5.2.1 - Operational range of the temperature probes:
Thermocouple K
: operational range from 0 to 999 °C
Thermocouple J
: operational range from 0 to 760 °C
PT100
: operational range from 0 to 849 °C
Outside these ranges the thermoregulator will signal an under range or over range error (see paragraph
